FIELD OF INVENTION

Large electronic displays, may be formed from an array of monitors referred to as a “video-wall”. For example video-wall might be comprised of a 3 by 3 array of nine monitor, each monitor simultaneously displaying a segment of a single image, thereby creating the appearance of a single large display comprised of rectangular portions.

The present invention relates generally to improving the setup and operation of large displays and particularly to network addressable video-wall displays.

BACKGROUND OF THE INVENTION

The present invention relates generally to improving the setup and operation of video-wall displays and particularly to network addressable displays.

A video-wall display system is a method to overcome the costs of manufacturing and installing very large displays, by assembling a large display using multiple smaller displays arranged and working together. By dividing a single image into several sub-images and displaying the sub-images on an appropriately arranged array of display devices a larger display with higher resolution can be created.

Because the plurality of display devices need to be operated together to display a single image or canvas across a video-wall (rather than a separate independent image for each display), the set-up of the output displays is critical and their fine tuning can be laborious. Informing the server of the initial positioning of each display (so that the image segments are sent to the appropriate displays); the precise cropping of each of the sub-images (to allow the eye to interpret continuity of the total image across the bezels of the displays where no image can appear); and the adjustment of the color of the sub-segments of the image to provide equal luminosity, color and intensity/brightness ranges across the whole array of displays within the video-wall, are all essential to providing the optimal viewing experience. With conventional approaches to video-wall setup these tasks can be laborious. This invention offers methods of automating the setup process to improve the ease and speed of video-wall setup.

DESCRIPTION OF THE INVENTION

A video wall server splits source-video into sub-images and distributes these sub-images to multiple listening display devices. Built-in algorithms optimize, parse and scale the individual video-wall segments. To accomplish this splitting efficiently it is beneficial to create a configuration file stored in a computer readable medium using information on the position, configuration and settings for each of individual physical display and how they relate to the video-wall canvas. Using such a configuration file allows the video wall server to efficiently create a seamless canvas across the display units. This invention deals with methods of supplying the information for the creation of such files by means of feedback based on test-canvasses and to sequentially changing the configuration file before redeploying a test-canvas to further improve the overall viewer-image.

Configuration of Displays: This invention provides methods equipping the server with a configuration file containing:

-   -   the overall shape of the video wall;     -   the ordering of the sub-images within the video wall;     -   any further rotation or displacement of displays required to         form the appropriate canvas on the video wall;     -   interactively fine-tuning the positioning and bezel width of the         displays to achieve perfect alignment across display monitor         bezels;     -   adjusting the color intensity of displays to achieve a uniform         color across the video-wall;         Once this information is established it is stored in the         server's configuration files.

The methods to achieve the five types of adjustments outlined above by automation presented typically involve a user interacting with the server via a GUI containing instructions and a camera in communication with the server. In a typical usage the user would have a smart-phone, tablet, laptop or similar device, interacting with the server via the web. The user giving permission to the server to use that camera to obtain digital images of the canvas as displayed across the video wall and the server giving instructions to the user about positioning he camera and where required to supply eye-based evaluation concerning the correctness of any changes to the displays made.

The server knows (via DPMS and EDID) certain details about each display (aspect ratio, number of pixels, etc.). Using these in conjunction with the image captured from the camera gives a unique ability to identify the exact positioning of the display.

The ordering and overall shape. Once the display units have been mounted to form the wall and connected to the server the server will know the number of display units involved and will analyze for shape. This can be accomplished by sending each display a unique computer-recognizable image. This could for example be a specialized “bar codes” designed for image recognition software (similar to QR codes). The image should have special symbols used to identify the exact spatial location of the corner pixels of each display. Next a message would be sent requesting the user to point the camera at the displays in the wall. Digital analysis of the image in comparison to the information as displayed allows the server to determine which displays are in the wall (some may be displaying in a different room), to identify the geometric placement of the displays (rectangular, linear or “artistic” (meaning in an informal non-geometric setup) and the position in which each signal sent appears in the display (which Ethernet or other connection leads to each display position). In addition it determines the rotation (do the images need to be rotated through 90 or 180 degrees and what rotations are needed for non-standard setups).

Once the digital image analysis has been completed the server would re-adjust the canvas presented across the screens and instruct the user to ready the camera for another image. This correction process would continue until the server's digital analysis was satisfied with the overall alignment, in addition it might ask for by-eye evaluation to confirm the result.

Interactive fine tuning of placement and rotation. Generally the canvas on the video wall will appear to be interrupted by the bezels making up the edges of each display monitor. The fine tuning is used to minimize the bezel effect by appropriately moving each of the displays a few pixel widths horizontally or vertically. For example this could be achieved by displaying a test canvas of diagonal lines on the video wall. The digital analysis being aware of the exact location of these lines in the canvas sent to the displays can examine the lines on the digital image very precisely for alignment and by calculation measure the number of pixels each display must be moved vertically or horizontally to achieve perfect alignment. Once these corrections have been made and a new canvas displayed it can be checked digitally and by eye.

Adjusting color intensity across the canvas. In a typical embodiment the next stage would be to check for color. The canvas might be such that each display contains the same pattern of rectangles each of a different color (perhaps red, blue and green) displayed with a range of intensities. Now the analysis is of each color intensity across all of the displays, so that any fine distinction between the treatment of a particular color/intensity combination can be adjusted for. Other tests of a similar nature can be used for particular differences between displays.

In an alternative and potentially complimentary method of calibration a moving image is output to the video-wall (for example horizontal and lines moving across the video-wall canvas) are captured and communicated in real-time by the camera and image analysis software interprets the captured frames to determine positioning.

The stage-wise process the methods outlined above are carried out in stages and at each stage the configuration file being used by the server is updated based on the new adjustments calculated, so that the end result is a file that can be used to promote perfect display of any video file presented to the server. Color calibration can be achieved in two possible ways.

In one embodiment of the invention color calibration is done by controlling monitor settings via the centralized server software being in communication with the display settings (potentially via an RS232 or other interface) and a uniform image canvas is output to the display. In an alternative embodiment color adjustments are stored in the server software and color adjustments are done by the server as it is output to the display itself. In the first of these cases the display settings are permanently stored on the server in a configuration file.

In one realization the same color is output on each of the displays within the video-wall and after each change in the display, an image is captured for analysis. This image analysis detects relative differences between each display and adjust color output characteristics on individual displays within the video-wall, successively adjusting hue, intensity and brightness of the individual images so that the same high and low values for each display are achievable by each of the individual displays within the video-wall, making the fine adjustments necessary to the color output characteristics and settings of each individual display.

In one embodiment of the invention the computer-recognizable images output to each of displays includes a right-angled line in various corners of the displays comprising the video-walls to aid in detecting the exact placement of these corners in relation to other display corners within the video-wall.

In another embodiment of the invention, component displays within the video-wall provide instructions to the user on how to connect their camera to the display (for example by providing a URL, to visit on their network-connected or Internet-connected device).

Visual prompting and status indicators to assist during video-wall setup. As displays are linked into a video-wall it is helpful to the individual setting up the video-wall to receive visual feedback from the displays themselves as screens are added to or removed from the video-wall. In one embodiment of the invention, visual status indicators shows progress as each display's position within the video-wall has been successfully identified and the display is “linked into” the video-wall. For example, a line, pattern, color change, picture, or animated effect is used to differentiate monitors which have been added or positioned within the video-wall from those that haven't. A different status indicator such as an image, icon, or input prompt could be output to those displays which are being output to by the video-wall server, but are still awaiting placement/assignment/relative-positioning within the video-wall. In one embodiment, once an an adjacency relationship is established between edges of displays within the video-wall a status indicates that the edges of both displays have been successfully linked. In one embodiment, once the full video-wall has been setup, will show a visual success image indicator spanning the full video-wall.

In one embodiment of the invention, in addition to the image data, the digital camera device also provides meta-data about the image. Data such as: camera orientation, detected ambient light, detected distance from the subject, focal length, shutter speed, flash settings, camera aperture, detected camera rotation angle relative to the horizon, GPS location. this additional data can be used to increase the accuracy or speed of image analysis or provide additional details about the video wall.

In one embodiment of the invention, a smart phone or other mobile device with an embedded camera device is in communication wirelessly with a video wall control server (which is in turn in communication with the video wall displays). The video wall control server outputs one or more optimized configuration images to the video-wall displays. Application code executed on the mobile device, either by the browser or by a native mobile device application) captures image data from said camera (this could be a still image, a stream of video data, or a sequence of still images) and forwards this image data over a wireless connection to the server.

An an image analysis module (could be either executed on the server or on the mobile device, or parts of the analysis could be performed by each) processes the captured image data

determining the display identity and placing each within the captured image then subsequently assessing differences in display placement, rotation, color, brightness, contrast, and other attributes of the various displays present within the capture image data. Via these comparisons the automated image analysis module is able to determine any adjustments required for mappings of various ones of the displays captured in the image and subsequently translate these adjustments into changes to the video wall configuration mapping file(s) or data stores. The updated mapping would then be communicated by the control module, in response to these changes to the server, server updates test images or sequences to the next test image, repeating any failed steps as necessary and moving to subsequent configuration tests as successful calibration of each unique configuration image is achieved.

In one embodiment the user is visiting a web-page with their mobile device (equipped with a camera), and the server is a web-server. That web-server also being in communication (able to send controlling signals) to the displays comprising the video wall. The displays being controlled by the web-server to output the configuration images.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates the basic problem. It shows a complex video wall layout (multiple displays arranged artistically at multiple angles). It also shows how the image output to each of these displays has been correctly aligned and correctly color calibrated so that the image displays correctly and evenly across on all screens regardless of their placement, rotation, spacing, bezel, etc. The 9 displays comprising the video wall are showing a test pattern illustrating the precise placement of the artistic display orientations within a video-wall. Once the physical video-wall displays have been installed. The mapping and placement of these individual displays within video wall canvas (10) the on the video-wall server can be accomplished by multiple means, however disclosed herein is an automated method for accomplishing this process adaptable even to complex non-standard video wall layouts such as this.

FIG. 2 illustrates the need for precise mapping, placement and bezel correction of displays when creating a video wall. The figure again shows a 9-screen video wall this time arranged in a 3×3 grid configuration video-wall presenting. The output image shown on the two video walls depicted is again an image of diagonal straight lines which have been drawn to span the whole video-wall canvas. In both versions the pattern is interrupted by the bezel edges of the nine displays which form pairs of horizontal and vertical interruption bands. However in the upper illustration of FIG. 2 (where the display placement within the video wall canvas has not been corrected/adjusted to account for bezel interruptions) you can see that the lines on the video-wall canvas do not align correctly hence to not appearing as portions of a single straight line. This is emphasized by the overlayed dotted straight diagonal lines (21) and (22). Notice that the lines on the non-aligned (non-bezel corrected) canvas do not exactly follow these ruled lines. The bottom half of the figure illustrates the view after effective bezel adjustments have been performed: the diagonals on the canvas line up accurately and the fine lines added at (23) and (24) confirm this. In practice such lines cannot be generated by the video wall server, and evaluation of alignment must be observed by a viewer either by eye or by automated image capture (method for which is disclosed herein).

FIG. 3 shows a schematic diagram depicting a 2×2 video wall comprising four independent displays working together to output a video wall that has been configured to correctly compensate for the display bezel. Also shown is a tablet computing device with a built in camera (31) which is being operated by a user (32) to capture an image of all four of the displays comprising the video wall (along with their output).

FIG. 4 illustrates in more detail the method of using a camera in combination with uniquely identifying output images along with automated image analysis to inform the server both of the identity of the individual displays in the video wall as well as the precise relative position and size of the displays in the video-wall. In this example, the video-wall server has output a different QR code to each of the nine displays comprising the video wall as seen in the top half of the FIG. (41). and it also shows a blown up enlarged view of one single display with the QR code (45) with corner markers (46) which would be a potential cue used as part of the system to help spatially locate edges and corners correctly through the image capture and analysis process. Also depicted is a schematic is a smart-phone or tablet equipped with a built in camera (42) being used to capture and relay images of the real-world video-wall output and relay it back to the video-wall web-server, allowing the video-wall server, through automated image recognition and analysis of the captured rendition of the output images, to correctly align and place the individual sub-image segments (and displays) within the video-wall canvas to create a mapping for use when outputting to the video wall. In one embodiment different images are output at different stages in the automated calibration process. For example at the next stage the server might output a line patter for precise calibration and use the image capture of a line pattern across the displays to automatically make the fine adjustments needed to allow for bezel corrections. Finally a color adjustment image (e.g., uniform colors across all displays) might be output across the video-wall using feedback from image analysis of the camera captured image to access differences in color output across various displays comprising the video wall. A second video wall is depicted in the lower half of FIG. 4 showing a non-rectangular video-wall (43) this time with a different type of identification and calibration image differentiating individual displays. Again the image of the video-wall is captured by a camera, in this case depicted as a mobile phone or tablet (44).

FIG. 5 shows a process flow-chart of automated video-wall calibration (50. Here (in step 51) video-wall is configured to output unique images to each of the unassigned displays within the system (some of which may be arranged into a video-wall). The user is then prompted (either on the displays or from within an administrative GUI potentially accessed from a mobile device such as a tablet, smart-phone, or laptop) to take a photo of the video-wall (step 52). In the case that the user is using a mobile device, the administrative web-application may request permission to directly access the mobile device's camera. The user then takes a photo of the video-wall and transfers this to the server for automated analysis (step 53). The server then (using automated image analysis of the specially output images) determines which display is arranged where within the video-wall and also determines the exact spacing, rotation. and placement of the displays by recognizing the distinctive identifying images in the photo and also by calculating the distances between each adjacent display edge within the photo (step 54). This information is then used to create a video-wall configuration file which is stored in a computer readable medium (step 55). A test pattern is then output to each of the displays comprising the video-wall (the displays that were contained within the photo taken by the administrator in step 52) (56), and it is checked for the accuracy of the completed step and reported either by an automated process or by a human observer (57). Subsequently further adjustments to this pattern are made if it is not satisfactory and a sequence of new test patterns analyzed (58) continuing until the total result is optimal and the process ends (59).

FIG. 6 illustrates the display adjustment process (60). The server outputs the appropriate (as needed at this stage in the process) unique identification images or color calibration image(s) to all the screens in the array (61) The user captures a live image of the screens (as requested by the server) (62). These are transferred to the server and analyzed (63). If both the user and server regard the results as satisfactory this step in the adjustment process ends (66), otherwise. The server adjusts the settings and or relationships between displays in the array based on results of automated image analysis (65) and outputs appropriate images at (61) once more.

FIG. 7 is an illustration of one specific embodiment of the whole video-wall system process of set-up and use with a networked video wall using zero clients. The user using a browser device with a camera authenticates as a user and authorizes the web calibration process (70). The server first discovers and connects to the zero-client devices over the network and builds a list of displays and assigns a unique identity to each display (71). Next it collects the available display resolutions and other available settings from all the connected displays (72). Then the automated setup process is launched beginning with a browser accessible GUI containing instructions for the user being launched on the user's web-browser device with an embedded camera (73). Initially the web-server requests permission to access to a camera (if permission in not granted the system will fall back to manual calibration methods). Once permission has been granted the user will be provided with instructions and real time feedback as needed throughout the whole process to assist them to correctly capture an image of the video wall (e.g., it may provide screen recognition features to ensure all screens have been captured from a usable angle). The process outputs unique calibration image optimized for automated image recognition to each display (e.g., QR codes with corner markers for initial identification image) (74). Capture image(s) and send to web-server for automated image analysis adjusting identification, positioning, and calibration settings and as required (75). The camera is controlled (either by the user or the web-server) to capture one or more images of the video wall of sufficient resolution to perform the required analysis (e.g., via html media capture or similar method). The images are transmitted to the web-server (wirelessly) for analysis by image analysis module (see flow-chart in FIG. 8). Further image data from the camera may also sent (such as orientation, ambient light, GPS, etc.). Update the settings file representing the positions and order of the display units as communicated in automated analysis. As needed throughout the whole calibration process update this file and update both the user instructions and individual displays as changes occur to this file. Check the results of the calibration (710) and evaluate if the current step is satisfactory in all respects (and if not continue calibration at (74)). If it is satisfactory, proceed to the next set of calibration images, for example line calibration images to fine-tune display placement or color calibration once no further calibration steps remain calculate canvas size and position of displays within canvas and write all sub-image mapping info to the settings file.

The preliminary steps in the setup of the video wall system are now complete and the system is ready to process and deliver content to the video wall displays. It can now receive content for display via the primary GPU processing application output frame by frame to the frame buffer (78), and process (e.g., crop/split/rotate/resize/color-convert) based on stored identity, placement, and calibration settings individual sub-image portions (79) to be encoded and sent to the appropriate devices for output to the appropriate secondary display adapters which in turn outputs the transformed image data to the corresponding displays (710), together creating displaying the video wall image across all displays. This decoding and displaying process is continued while the video-wall is in use (711), and ends when terminated (712).

FIG. 8 is the flow diagram for an image analysis and detection module. The process begins at (80) and starts by receiving image(s) from camera device and the display information appropriate to the displays that formed the canvas for the camera (81). It analyzes the newly received image for recognized markers and match to existing data (82). It performs initial checks on the image and provides error messages to the user as required (e.g., does the number of displays in the captured image match the number of detected displays in communication with the web-server? Is the angle, clarity, and resolution of the image sufficient for automated detection routines?) (83). Next it matches the geometrical model of the video wall (either pre-existing model built at an earlier stage in the automated setup process or built by combining the data retrieved from output to the displays with the display positioning and sizing information obtained through image analysis (84). Next the process isolates the captured display area of each detected display and analyzes the image data from each display (85); and utilizing the spatial information from the captured image automatically determines the placement of this display (86). By comparing the captured display area of each of the plurality of displays for perceived differences in the unique configuration images (87), it determines the adjustments to the mapping settings as required for the identity, position, size and output characteristics of the plurality of displays visible within the captured image (88), It returns the adjusted mapping settings for the plurality of displays based on required adjustments determined in the previous step (89). This ends the current step in image analysis (810) and allows a new new and better canvas to be displayed using the modifications to the updated configuration file.
